The Holley cast aluminum Modular Hi-Ram™ Intake System fits GM LS3/L92 engines and is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. The base is a modular design to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems. There are four tops: a forward mount throttle body style, dual 4150™, dual 4500™, and a blank top to machine for any induction style.

The runner length and tapered cross–section are designed to perform well for a wide range of engine configurations from street to race. The LS Hi-Ram™ intake system is intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range with max power at 7,000-8,000+ RPM.
